IMPROVEMENT INl CASTING METALLIC `Cl--l EESE-HOOPS.

' Specilieation forming part of Letters Patent No. 19.677. dated Mai-0h23. 1855 To all whom, it may concern:

Be it known thatl, TIMOTHY BROWN, of Georgetown, in the countyof Madison and State of New York, have invented a new and Improved Mold for Casting Metallic Cheese- Hoops; and I do hereby declare that the following is a full and exact description thereof, reference heilig had to the accompanying drawings, making part of this'speciiication- Figure l being a plan ofthe mold; Fig. 2, a corresponding plan,'the top being removed; Fig. 3, a vertical. section through the center; Fig. 4, an elevation of the inner part of the mold,l looking from the left, when in the position shown in ,Fig 2; Fig. 5, an elevation thereof, looking from the bottom of the sheet, when in the same position; Fig. 6, an elevation of the inner side of the-outer part of the mold.

f Like letters indicate corresponding parts in all vthe figures.

I cast the hoops in halves to be hinged to gether, the two halves being exactly alike, so that the same mold is, adapted to casting both.

Theobject of the improvement is so to construct the mold that the halves, although precisely alike, shall t together properly to conipose a suitable hinge at one joint, and a suitable firm connection to be opened and closed at pleasure at the other. joint, and to accomplish this with great facility and rapidity;

The inner part, A, of the mold consists of a cylinder of metal of the proper lheight and` diameter to,l produce a cheese-hoop of the dei sired size.V An annular plate, is secured to the lower-end of the cylinder, projecting outward in the form of'zil iiange sufficiently vwide to serve as the bottoir of the mold. It may also project inward beyond the cylinder. On

opposite sides oi' the cylinder are two projections, .b b, which serve as endpieces for molding the extremities of the half-hoops,'and for holding-the outer removable part, B, of the mold inl place; On the side ofthe cylinder A where the hoops are to be cast the distance between the projections b b around said cylinder is just half of the circumference thereof. The outer part, B, of the mold consists of a halfcyli'nder or a little more, sufficient to produce the proper lap at one cnd over one of the projections b,which is beveled for the purpose, as seen at the right hand in Fig. 2. The cylinder of the outer part, B, is enough larger than that/ol' the inner part, A', to leave the proper space between them for the hoop. The height of both parts is the same. One end of l[he inner part is formed into a number of tubes,

7i h h, all'in the same vertical straightliuc,

with an equal number of spaces, 'i it, alternating therewith, substantially as shown in Figs.

.3 and 6. The apertures of the tubes are of proper size for the pivot of the joint where the halves are put together, and the diameter and length of the hollow spaces-zi t are the same as of the tubes h h h, and all uniform. There isan equal number of tubes and spaces, so that a tube will terminate one edge of the `mold-piece and a space terminate theother l edge thereof. rlhe other end of the moldpiece B has a lip on its outer edge, andthe inner edge thereof is beveled, so as to t closely over thebeveled face of the projection b of the inner mold-piece, A. 1 There is a shoulder, g, just at the center of the' thin edge of said projection l), substantially as shown in Figs. 2'

and 4, for the purpose of producingaproject ing lip on one h'alf of the breadth of the hoop at the end, and a corresponding depression in the inner edge of the end for .the remaining half .O'f the width, so. that when the two halves of the hoop are shut together the two ends cannot move or slide, one by the other, either vertically or radially. Suitable depressions, rc., Z l l, are formed in or on the inner surface of the outer mold-piece, B, for thepurpose of producing any ribs, beads, or ornainents desired. The top of the mold is a separate piece, C, in the fornrof an annular plate of the same size as the bottom c.. It has an annular groove in its under side, leaving a vportion inside thereof just equal in diameter to the inside ofthe mold-piece A considerably thicker than the rest of the top, so that when said top is placed on the mold saidthick portion will iit into the cylinder` A, Vand thereby keep the top in the proper position. Apertures f f, Fig. l, are made in it,-t.l1rough which the melted metal is to be poured. A hole is made in the bottom a, and another inthe top C, exactly in a line with the hinge-tubes h h h when the inold-pieceB is vplaced in its proper position, where it is held by passing a rod, c, through said holes in the top andbottom and through the l'tubes h h h, as shown in Fig. 3. The rod fits closely in the tubes h h h, and together therewith. and with the spacesi serves to produce the hinge of the exact form required. The other. end of the mold-pieceB is held in place by a rod, d, passing down through holes in the top and bottom, and just outs-ide of the lip ou the end ofA said moldpiece. After the metal is `poured in and solidified, as indicated'by the blue color in Fig. 2, the rods c d are withdrawn, and the moldpieces A B separated, which leaves the halfhoop completely formed. The mold vis then again put together and another half-hoop cast, and thus the process is contined with great rapidity. To complete the hoop it is only requisite to put a rod through the hinge-joint after putting two halves together, and to secure a Suitable clasp to the unconfined edges for fastening them together.

lVhat I claim as my invention, and desire to secure by Letters Patent, is-

'The combination of the cylindrical guiding and supporting mold-piece A, provided with thelaUge-bottom a and side projections, b b, the semi-cylindrical.mold-piece B, and the guide itop C, all arranged -in relation to each other as described, and united by the rods c and d, substantially in the manner and for Witnesses;
